Power Supply
The Gallagher T10 Mifare Reader is designed to operate over a supply voltage range
of 9 - 16 Vdc measured at the reader terminals. The opera ng current draw is
dependent on the supply voltage at the reader. At 12 Vdc the current draw is 82 mA
(standby). During card read, beeper and LED ac vity, the current will momentarily
reach 115 mA (peak).
The power source should be linear or a good quality switched-mode power supply.
The performance of the reader may be aff ected by a low quality, noisy power supply.
Cabling
The Gallagher T10 Mifare Reader requires a minimum cable size of 4 core
24 AWG (0.2 mm
2
) stranded security cable. This cable allows the transmission of
data (2 wires) and power (2 wires). When using a single cable to carry both power
supply and data, both the power supply voltage drop and data requirements must
be considered. Although the reader is specifi ed to operate at 9 Vdc, for good
engineering design it is recommended that the voltage at the reader should be
approximately 12 Vdc.

* The matching of wire sizes to equivalent wire gauges are only approximate.
Grounding shielded cable may reduce the obtainable cable length by 25% to 30%.
